Abstract
A high pressure discharge lamp (), which is particularly a motor vehicle headlight, comprises a high pressure discharge burner () for emitting light supported by at least one leg (), preferably three or four legs (). By means of the legs () the burner () is mechanically connected to a socket () of the high pressure discharge lamp (). According to the invention the legs () are part of a holder (), which comprises further a ring () surrounding the socket (), whereby the ring () is one-piece with the legs (). Due to the design of the holder () as ring () with protruding legs () the heat of the burner () is conducted from the burner () via the legs () to the ring () by heat conduction. From the ring () the heat is led away to the environment by convection. This leads to a significant cooler Temperature of the holder () with respect to the burner (), so that the material of the socket () needs not to be selected with respect to a good heat resistance. Thus, the use of more cost efficient materials is possible to deal with the hot burner ().
